    Hi Cooper,

    To my knowledge, TI does not have a device that can output current of that magnitude.  Generally, we recommend a precision DAC with a high-side or low-side current source.

    Take a look at this reference design for an example on how to do this.  You could also take a look at our DAC53701 device, which can be used as a high-side current source very easily.

    Thanks,

    Paul
